Changelog: [internal]
There is a possibility of race between updating scrollview's state and virtualised list asking for layout of individual cells.
To make sure the race doesn't happen, state must be updated before dispatching onScroll event.
Android has implemented a different mechanism to tackle this issue in D28558380 (b161241db2).

This is a mechanism that will guess event's React priority based on other events ongoing on the platform.
If an event happens within span of ContinuousStart -> ContinuousEnd and its category is unspecified, we deduce it's React priority to be default. All other events are discrete.
Special case: `onScroll`, which is always treated as "Default".

Summary:
TL;DR: simplify and delete a bunch of stuff that shouldn't be necessary in Fabric.
I discovered that this event dispatcher (and the older one this is based on) is triple-queueing: we queue events into "staging", and then post "dispatch events" to only run /on the JS thread/. Even in Fabric. Then, each of these events is emitted into C++ where they are queued /again/! This refactor eliminates one more level of queueing - instead of scheduling dispatch for the JS thread, we just emit them directly to C++ when they're received in Java.
Unfortunately, the EventDispatcher is also used to drive AsyncEventBeat in C++:
1. EventBeatManager.onBatchEventDispatched: https://fburl.com/diffusion/qf6dyhsw
In the C++ impl, it indirectly will drive the AsyncEventBeat/AsyncEventBeatV2.
2. onBatchEventDispatched is ONLY called from EventDispatcherImpl: https://fburl.com/codesearch/mxk8ifyj
3. Which is queued and only runs on the JS thread: https://fburl.com/codesearch/czvbst4u
This means the AsyncEventBeat is only ticked when the JS thread is free, and ticks will be skipped when the JS thread is occupied for long periods.
Now, in this refactor, when this class is used it will drive AsyncEventBeat on every UI tick. This is also potentially not correct. On iOS (Fabric), AsyncEventBeat is driven when the UI thread is "about to sleep".
For now I'm not going to worry about that detail - it is significant, but Fabric+Android is currently /not doing the right thing/ and it's not clear that we want to maintain iOS behavior. This is something we need to discuss further and figure out.

Summary:
`isColorMeaningful` is the only place in xplat code that currently uses `colorComponentsFromColor`, which assumes that a color is an RGBA value. When implementing `PlatformColor` for windows, where colors might be complex patterns or effects, I'd like to keep the details of `SharedColor` isolated within `SharedColor`. This change moves `isColorMeaningful` into `color.cpp`, where each platform can provide an implementation that takes into account its platform specific color capabilities.
See https://github.com/microsoft/react-native-windows/pull/7801 for an example of window's SharedColor which can be either an RGBA value, or a name of a native color/brush.

Summary:
Changelog: [internal]
My suggestion is to simplify event dispatching to only two options, synchronous and asynchronous.
Why?
- Fabric has only been using one queue, `AsynchronousBatched`.
- Batching happens even on `AsynchronousUnbatched`. It just batches events until JS thread starts processing them instead of waiting for the main run loop.
- It will make it easier to reason about the code in the future once we start utilising different priorities for Concurrent Mode.

Summary:
FlatList relies heavily on onScroll events + the measure API. In Fabric, usage of `measure` relies on C++ having an accurate view of the current scroll position of the ScrollView.
We already have a mechanism for updating the scroll position in C++ using UpdateState. But, it is only used currently at the /beginning/ and /end/ of scrolling, and UpdateState is not called /during/ scrolling at all.
This means that we will see a series of events like this while scrolling:
```
Scrolling begins
UPDATE C++ STATE: scrollLeft = 0, scrollTop = 0
JS event: onScroll x=0, y=0
JS event: onScroll x=0, y=100
JS event: onScroll x=0, y=200
...
JS event: onScroll x=0, y=1000
UPDATE C++ STATE: scrollLeft = 0, scrollTop = 1000
```
Notably, not many C++ state updates are queued; and the last one is queued AFTER the JS event is sent. The last JS event and UpdateState will race, which means that sometimes the C++ update will /lose/ and C++ will have an inaccurate view of the world when FlatList receives the onScroll event and calls `measure`.
My proposed solution, gated behind a feature flag, is to delay /some/ onScroll events until the C++ UpdateState has made its way back to Java, and send UpdateStates more frequently. The balance here is that UpdateState is a relatively expensive operation, so we probably still want to call it /less/ than we call onScroll. This means that `measure` will still return some incorrect results but will return correct results more frequently. Win?

Changelog:
[iOS][Added] - Description
When compiling iOS apps with flag `-Wnullability-completeness` (like Lightspeed app and soon Instagram), Objective-C headers are required to either have full *explicit* nullability annotations on all members of its public API, or none at all; partially annotated headers will fail to build that module.
RN native modules are currently generated with *partial* annotations. This works today because most apps are not compiled with `-Wnullability-completeness` turned on. But when we flip the switch for Instagram, the app doesn't build due to importing these RN partially annotated modules.
JavsScript Flow types are implied nonnull, and the current RN codegen translates Flow's [maybe/optional](https://flow.org/en/docs/types/maybe/) type to Obj-C `_Nullable` annotation, and everything else without an explicit Obj-C annotation. However this creates a mismatch with the Obj-C type system, where the implied default is *unannotated*, which is handled differently from nonnull when built with the nullability compiler flags.
There is a simple Obj-C macro that automatically adds *explicit nonnull* annotations to all members in a header: `NS_ASSUME_NONNULL_BEGIN` / `NS_ASSUME_NONNULL_END`. If we add this to *all* RN-generated headers, however, we run into issues:
1) We may erroneously assume any previously-unannotated header was meant to be nonnull and cause future bugs
2) Another compiler flag (`-Wnullable-to-nonnull-conversion`) statically analyzes Obj-C implementation code to prevent us from ever passing null to one of these headers. Much existing Obj-C code will break here, and it's ambiguous if these are true or false positives because of the first point.
Instead, in this diff we add a new BUCK flag `ios_assume_nonnull` to let module authors opt into automatic nonnull for unannotated members so that Obj-C headers are generated correctly in alignment with Flow's type system. We can migrate all libraries individually as needed and eventually make this the RN native codegen default.
